Experience with alphacool

[VINCEindaHOUSE]

Been thinking about buying a alphacool rtx 3090 strix waterblock. Does anyone here have any experience with them

I don't have any personal experience with the waterblocks.  I have 3 rads and one of the pump blocks from alphacool though and my experience with those has been mixed.  The 3 rads have been perfect, they were clean when they arrived, fit/finish is good and have had zero issues with them cooling my system for almost 4 years now.

 

The pump block was a whole different story and just about killed my pc.  I had gotten one of the Eisdecke D5 Brass pump tops.  Not sure if me running cleaning solution through the system caused it or some incompatibility with Ek Cryofuel liquid is what killed it but almost all the black finish pealed off the inside of the pump cavity and proceeded to block all my cooling blocks.  It took 3 years of 24/7 use and system flushes before this happened so I can't put a finger on what the cause could have been.  It was a proper frigging mess to purge all that crap out of my system though.  None of the black finish came off the rads or any of the fittings, just the pump block. I would still use their stuff if needed but personally would skip anything that had a painted or powdercoat type finish on the inside surfaces.
